Application September 28, 1951, SerialNo. 248,826

7 Claims. (01. 3sv 4s) l v invention relates to an archery sight: for along bow. In prior application serial No. 77,881, filed February 23,1949, Patent: 2,542,501, granted February 20, 1951, there is disclosedmeans for H which are received within and engaged against an arcuate,longitudinally extending guideway provided in the hand grip.

Accordingly, it is an object of this invention to provide a novelmounting structure fora sight base which is particularly adapted toprovide a rigidsupport for the sight base on the hand grip.

Another important object is to provide reticle markings on a plateassociated with a lens structure embodied in the invention, said plateand lens structure-being so arranged as to permit accurate sighting atwidely varying ranges without adjusting the position of the lens mountembodied in said structure.

Another object of this invention is to provide a mounting structure fora sight base'which is particularly adapted to' support a sight base in aselect, relatively rigid position along an arcuate path, and permitmovement of said sight base to any other select position along said pathsimple in structure and cheap tomanufacture.

The above and still further objects and advantages of the invention willbecome apparent upon consideration of the following detailed descriptionof the invention, when taken in conjunction with the accompanyingdrawings,

wherein:

Referring now more particularly to the drawings, wherein like referencenumerals; have'been used; hr ughout the several views to desi na likeparts, there; is. shown the. archer-y sight of the present invention,generally indicated by the reference numeral H], which embodies a handgrip H detachably secured between the upper and: lowerbow sections I2and I-3, by-any suitable means such as the screws l4. Connected betweenthe free ends of the sections l2 and I3 is a bowstring l5 for theprojection of; an arrow: {6,Figure 7.. 9

Intermediate its ends, the hand; grip. l I is provided; with avertically disposed guideway which by securing a cover plate it providedwith an' elongated arcuate slot 22 over the open mouth ofthe recess byany suitable-means, such as the screws 23.

Positioned exteriorly" of and transversely of the hand grip l-lcontiguous to the cover plate 2| is a, sight base 25 which is supportedon suitable mounting means 26; for. movement along the guideway ll. Themounting means 26 embodies a pair of pressure plates or abutments 21 and2&positioned within the-guideway'l-l in side.- by-sidaspaced,confronting relation with respect to each other. Carried by theconfronting face ofzthe abutment it ar t pi s 29: and 3fl' h have theirfree ends received in suitable recesses. provided in the confrontingface of the A's clearly" shown Figure 5, the

pins 29 and 3lliareneut away to provide bores for the reception andsupport therein of the-springs '31" and 32; which. ar ci cump bmihe p279 and; inland urge the non-confronting faces of the abutments 21 and28 intobearing engagement with the arcuate side walls 19 and 20 of theguideway ll. The abutment plates 21 and 28 normally provide a relativelyrigid support for the sight base on the hand grip II, but permitmovement of the sight base to any other position along the guideway uponthe application of an upwardly or downwardly directed pressure to thesight base.

Arranged transversely of the hand grip H is a pin 34 which has one endextending into the guideway I! and secured to the abutment 28, an hasthe other end threaded and rotatably supporting the sight base 25.

As clearly shown in Figures 3 and 4, the bounding portions of thearcuate' slot 22 'of the guideway I? are cut away transversely inwardlyand at an angle with respect to the exposed face of the cover plate 2|to provide a seat 36 diverging outwardly fromthe outer face of the,cover plate 2!. Surrounding the pin 34 is a thrust bearing 3'! which isbiased into engagement with the seat by'means of the coil spring 38which is operatively connected to the pin and to the hand grip, the coilspring 38 normally urging the abutment 28 into bearing engagementagainst the base wall I8 of the guideway H. To further insure theengagement of the thrust bearing 31 with the seat 36, a small coilspring 39 has one end operatively connected to the thrust bearing 31 andhas the other end received within a bore 40 provided in the abutment 28,the spring 39 being clearly shown in Figure 3.

I As clearlyshown in-Figures 3 and 4, the sight base 25 embodies acylindrical locking member 42 which is provided with a transverselyextending, threaded bore 43 for the extension therethrough of theadjacent threaded end of the pin 34 to thereby rotatably support thelocking member 42 for rotary movement about the pin 34 as a pivotalaxis. Engaged above and supported upon the locking member 42 is'thesupport 44 of the sight base 25, the support 44 being' provided with acylindrical seat 45 for the reception of the locking member 42. The pin34 and the locking member 42 cooperate to support the support 44 of thesight base 25 for vertical adjustment. Suitable means are carried by thesupport of the sight base and are operatively connected to the pin 34for securing the 41a of the set screw 41 abutting against the outer faceof the support 44. Arranged at opposite sides of the headed set screw 4!are the small set screws 49 and 50' which are threadedly supported inthe support 44 and engage in recesses formed in the periphery of thelocking member 42 to preclude movement of the support 44 with respect tothe locking member. Accordingly, the archer, having determined thevertical angulation and locked the support 44 by tightening the screw41, can be assured that the set screws 41, 49 and 50 will hold thesupport 44 and locking member 42 against relative movement in theselected position of adjustment to which they are moved about the axisof pin 34 in obtaining said vertical angulation.

Carried by the sight base is the sighting means which embodies a plate52 and a lens structure 53. The plate 52 is carried contiguous to t rearend of the support 44 of the sight base 25, and is inclined at, an anglewith respect to the support.

Asshown in Figure 3, the front face 54 of the plate 52 is provided withreticle markings 55, the reticle markings including white lines on adark background. As will be noted from Figure 2, the markings compriseavertical seriesof three dots with straight lines extending between thedots of said series, and a similarly joined, horizontal series, thecenter dot of the respective series being common to both series. Thelens structure 53( embodies a lens mount 56 carrying a lens 51,

the lens being disposed in spaced, confronting relation with respect tothe front face 54 of the plate 52 and providing a means for sighting atarget and'for visually displaying a virtual imsmallV-shaped notchistogive an emergency.

point of aim in event ofthe failude of the reg? ular sight formed bythe-cooperation of the plate 52 and the lens structure 53. 'A portion of*the hand grip contiguouslto the lower end thereof is provided with arubber covering 60, the covering being secured to the hand grip andforming a non-slip grip for the archer.

As clearly shown in Figure 6, the portion of the hand grip intermediatethe cover plate 2! and the rubber cover 60 is provided with atransversely extending recess. 62 which is disposed means, such'a's aslot,- for conveniently turning I the setscrew. 'Upon effecting therotary move- .ment of the set screw; the slide, together with the arrowrest, may belocked in select positions of the lateral adjustment withrespect to the hand grip. V J r In actual use, Figure '7 shows a line ofsight from the archers eye to a target 61, the line of sight beingindicatedby the reference numeral :68. However, the particular sightsetting shown ,inFigure 7 may not be correct for hitting the target 61,whereby it will be necessary to tilt the bow forwardly or rearwardly.Thus, the

archer changes the sight setting by pressing on V the sight base 25 tothereby effect the movement of the abutments 2 1 and 28 along theguideway The surface of the hand grip adjacent slot 22 is provided withrange graduations 69 to facilitate correct adjustment of the abutmentsalong the guideway. In view of'the fact that the support 44 of the sightbase 25 can be fixedly secured in a desired angular relation withrespect to the hand grip, the aforementioned .movement' will change theangular relation of the base to the bow. In this connection, the

radius of curvature of the slot 22 approximately .equals thedistancefrom' the. eyeof theuser to the. sight.
